[PATCH 3/4 RESEND] spi: s3c64xx: simplify suspend / resume handlers

[Heiner Kallweit <hkallweit1@gmail.com>]

The runtime PM suspend / resume handlers take care of the enabling/
disabling the clocks already. Therefore replace the duplicated
clock handling with pm_runtime_force_suspend/resume.

Changed:
- Replaced pm_runtime_suspend/resume calls with their
  .._force_.. equivalents.
